The rectangular area *MNPO* and *QRTS* each measures 60 × 90 sq. *aṅg*. and can accommodate 6 *B*₄s each. In the central row 14 *B*₄s can be arranged as shown, leaving two isosceles triangular spaces of side 30 *aṅg*. Kapardi calls the central row *viṣayānāṃ mārga*, as bricks at the junctures (*apyaya*) partly lie on either side; he also confirms 14 *B*₄ bricks in this row—*viṣayānāṃ mārge tiryagātmani caturdaśa caturthyaḥ* / The space available in the head together with the two isosceles triangular areas can be exactly filled with 4 *B*₄ bricks as shown. The number of bricks and their types in the different parts of the fire-altar are given in Table 5.
